CON VEYER.

To all fro/0m t may concern Be it known that we, ARTHUR BUReEss, asubject of the King of Great Britain and Ireland and the Isle of Man,and JOHN G. EHFUss and MARTIN O. Rnriruss, citizens of the UnitedStates, all residing in Philadelphia, county of Philadelphia, State ofPennsylvania, have invented certain Improvements in Conveyers, of whichthe followingv is a specification.

ur invention relates to certain improvements in conveyors, particularlythose used for feeding or conveying materials, such as fabrics, to afolding or other machine.

One object of the invention is to construct the chain so that the linkswill be universally connected; one link being free to turn independentlyof the other.

A further object of the invention is to provide a link with a projectingflange, which may be used .as the driving flange, and also to providepins, or other projections, on the flange for engaging the fabric, orother goods, to be conveyed.

In the accompanying drawings :-Figure 1, is a longitudinal sectionalview of our improved chain; Fig. 2, is a view showing our improved chainpassing around a sp-rocket wheel and through a tube; Fig. 3, is asectional view on the line 3&3, Fig. 2; Fig. 4, is a perspective viewillustrating the chain and guide tube, and Figs. 5, 6 and 7, aresectional views showing the chain in diiferent positions in the guidetube.

are the links of the chain. Each link at one end a ball a and at theopposite end a socket o, in which is mounted the ball of an adjoininglink. The balls are connected to the body of the link by necks a and, inthe present instance, the fiange b of each socket portion is crimpedover the end of the ball so as to firmly connect the links together, butthere is sufficient space to per mit of lateral movement of the ball inthe socket; the ball being free to turn in the socket so that there is anecting each link of the chain. On each link is an annular iiange c.This fiange can be of any width desired and not only acts as a guide forthe cha-in within the tube D, but also acts as the drive flange for thechain.

The sprocket wheel E hasteeth e between which rest iangcs c of the linksof the chain and the end curved to conform tooth is preferably to theshape of the body portion of the link. The guide tube D has alongitudinal slot on the anges c of the instance, are pins the slot, asclearly shown in T e pins are and if the slot is the pins will travelturn its links, as illustrated d therein and mounted links, in thepresent which project through Figs. 2 and 5.

particularly adapted for guiding fabrics, which projecting pins and whenwith the curved slot is Fig. 2 of the dra-wings, feeds the fabricforward, int, automatically releases the fabric. In other instances itmay be used to stretch the fabric during an interval of its travel,while the fabric.

such

as lace curtains,

but it will be understood that the invention can be used as a means forstretching fabrics, or may be used for other purposes.
